The Simulation and Analysis of Quantum Radar Cross Section for Three-Dimensional Convex Targets
IEEE Photonics Journal, 2018Co-Authors: Chonghua FangAbstract:Quantum radar offers the prospect of detecting, identifying, and resolving RF stealth platforms and weapons systems, but the corresponding quantum radar cross section (QRCS) simulation is restricted-almost all existing methods can only be used for the two-dimensional (2-D) targets, not the 3-D targets even for convex targets. We propose a novel method that can deal with the calculation of the orthogonal projected area (A⊥) of the target in each incidence, which is the key part of QRCS simulation for the arbitrary 3-D convex target. To the best of our knowledge, this has not been reported before. In this paper, we introduce a three-step computation process of (A⊥), and verified the method for typical 2-D targets. Finally, we show some results for typical 3-D convex targets and compared the QRCS with classical radar cross section (CRCS). Meanwhile, we analyze the superposition of quantum effect of side lobes for 3-D convex targets. The proposed method provides a key improvement for realizing the Universalization and utilization of QRCS calculation.

Universalization of access to modern energy services in indian households economic and policy analysis
Energy Policy, 2009Co-Authors: Sudhakara B Reddy, P. Balachandra, Hippu Salk Kristle NathanAbstract:Provision of modern energy services for cooking (with gaseous fuels) and lighting (with electricity) is an essential component of any policy aiming to address health, education or welfare issues; yet it gets little attention from policy-makers. Secure, adequate, low-cost energy of quality and convenience is core to the delivery of these services. The present study analyses the energy consumption pattern of Indian domestic sector and examines the urban-rural divide and income energy linkage. A comprehensive analysis is done to estimate the cost for providing modern energy services to everyone by 2030. A public-private partnership-driven business model, with entrepreneurship at the core, is developed with institutional, financing and pricing mechanisms for diffusion of energy services. This approach, termed as EMPOWERS (entrepreneurship model for provision of wholesome energy-related basic services), if adopted, can facilitate large-scale dissemination of energy-efficient and renewable technologies like small-scale biogas/biofuel plants, and distributed power generation technologies to provide clean, safe, reliable and sustainable energy to rural households and urban poor. It is expected to integrate the processes of market transformation and entrepreneurship development involving government, NGOs, financial institutions and community groups as stakeholders.

A Novel Ionospheric Sounding Radar Based on USRP
IEEE Geoscience and Remote Sensing Letters, 2017Co-Authors: Ziyang Zhao, Xiaohua Deng, Kai Yuan, Huixia Li, Zheng WangAbstract:Ionospheric sounding is a technique that provides real-time data on high-frequency ionospheric-dependent radio propagation. This letter presents a Universal Software Radio Peripheral-based ionospheric sounding radar, which relies on a basic system consisting of a synchronized transmitter and receiver. The radar has the advantages of miniaturization, modularization, low power, and low cost. The three most significant features of the radar system are that it is software-defined and universal platform-based and that it has low transmitting power. This novel software-defined vertical-incidence radar system can probe the ionosphere and obtain real-time plasma parameters according to the simulation. Ionograms that directly express probe results are generated by MATLAB after data processing and simulation. Successful development of such an ionospheric sounding software radar will allow Universalization and miniaturization of an ionosonde radar system. This letter introduces the implementation of the novel ionospheric sounding radar.

sustained reduction of childhood diarrhea related mortality and hospitalizations in mexico after rotavirus vaccine Universalization
Clinical Infectious Diseases, 2016Co-Authors: Edgar Sanchezuribe, Marcelino Esparzaaguilar, Umesh D Parashar, Vesta RichardsonAbstract:BACKGROUND: Mexico implemented routine childhood vaccination against rotavirus in 2007. We describe trends in hospitalization and deaths from diarrhea among children aged <5 years in Mexico before and 7 years after implementation of rotavirus vaccination. METHODS: We obtained data on deaths and hospitalizations from diarrhea from January 2003 through December 2014 in Mexican children <5 years of age. We compared diarrhea-related mortality and hospitalizations in the postvaccine era with the prevaccine baseline from 2003 to 2006. RESULTS: Compared with the prevaccine baseline we observed a 53% reduction (95% confidence interval [CI] 47%-58%) in diarrhea-related mortality and a 47% reduction (95% CI 45%-48%) in diarrhea-related hospitalizations in postvaccine years translating to 959 deaths and 5831 hospitalizations averted every year in Mexican children aged <5 years. Prevaccine peaks in diarrhea-related mortality and hospitalizations during the rotavirus season months were considerably diminished in postvaccine years with greater declines observed during the rotavirus season compared with non-rotavirus season months. CONCLUSIONS: We document a substantial and sustained decline in diarrhea-related hospitalizations and deaths in Mexican children associated with implementation of rotavirus vaccination. These results highlight the public health benefits that could result in countries that adopt rotavirus vaccination into their national immunization programs. (c) The Author 2016.

Structure and Strategy within Heterogeneity: Multiple Dimensions of Regional Networking
Regional Studies, 2008Co-Authors: Michael Steiner, Michael PloderAbstract:Clusters are highly differentiated across sectors, regions and countries – both theoretical and empirical approaches therefore have to avoid Universalization. Based on recent approaches various forms of network relations and possible contents of interactions of firms connected with knowledge exchange are elaborated. It will be argued that these interactions are distinctively structured, that the diffusion of knowledge is highly selective and strongly dependent on the position of firms within networks and on their absorptive capacity. By applying network analysis to different dimensions of interactions between firms it is shown that physical linkages within the medium technology cluster under scrutiny are rather weak, that interactions based on different forms of knowledge exchange are denser, and that direct links to the science base seem to be more prominent than long term supplier networks.
